Genetics Vocab Quiz 23-24 (1st/2nd)

A long, continuous thread of DNA that consists of numerous genes and regulatory information

• Chromosome

• Haploid

• Meiosis

• Codominance

Tags

NGSS.HS-LS3-1

Any of the alternative forms of a gene that occurs on a specific place on a chromosome (Ex/ T=brown hair, t=blonde hair)

• Crossing Over

• Allele

• Haploid

• Pedigree

Tags

NGSS.HS-LS3-1

NGSS.HS-LS3-2

Heterozygous genotype (ex/ Ww)that is a blend of two homologous phenotypes (i.e. White x red flowers= pink flowers)

• Incomplete Dominance

• Full dominance

• Gregor Mendel

• Codominance

Heterozygous genotype (ex/ Ww) that equally expresses the traits from both alleles (i.e. Red cow x white cow = white cow with red spots)

• Chromosome

• Gamete

• Codominance

• Incomplete Dominance

Exchange of chromosome segments/genes between homologous chromosomes during Meiosis -- leads to an INCREASE in genetic variety.

• Translation

• Crossing Over

• Mitosis

• Transcription

Tags

NGSS.HS-LS3-2

Cross, or mating, between organisms involving 2 pairs of contrasting traits

• Dihybrid Cross

• Monohybrid Cross

• Meiosis

• Mitosis

Allele that is expressed when 2 different alleles are present in an organism's genotype.

• Codominance

• Recessive Allele/Gene

• Dominant Allele/Gene

• Incomplete Dominance

• Brain Cell

Tags

NGSS.HS-LS3-1

NGSS.HS-LS3-2

Specific region of DNA that codes for a specific protein/trait

• Somatic Cell

• Haploid

Tags
